Subcutaneous vs IV for heroin method

[starspangledstammer]

I've decided to use this as my method. Ive read about the unreliability of it but am gonna go with it anyway. My biggest fear is that I won't be able to get everything injected before I pass out. I was considering doing a subcutaneous injection for this reason because I know that still has high bioavailability but would give me some time before I go unconscious. Is this a good idea?

SubQ heroin (not even fent?) is extremely unlikely to kill you. You'll probably just wake up with an abcess.

But I heard it has close to 100% bioavailability
